Display Casing Capable of Accommdating LCD Panel Modules of Different Sizes

1. A display casing capable of accommodating LCD panel modules of different sizes, comprising: a rear casing including a plurality of first positioning portions disposed on an internal side of the rear casing, wherein the first positioning portion is a protrusion body erected on the rear casing and includes at least one first hook portion disposed in the protrusion body; a plurality of adjusting portions each including a support stand and an elastic plate, wherein at least one second positioning portion is disposed at a distal side of the support stand and coupled with the first positioning portion, such that the support stand is fixed onto the rear casing, and the elastic plate is fixed onto a lateral side of the support stand; the second positioning portion includes a second hook portion disposed at a position corresponding to the first hook portion, such that when the second positioning portion is embedded into the first positioning portion, the first hook portion and the second hook portion are coupled and fixed together; and when the second positioning portions of the adjusting portions are connected to the corresponding first positioning portions, the elastic plates of the adjusting portions form an enclosed accommodating area for accommodating an LCD panel module inside the accommodating area, and the elastic plate abuts against edge of the LCD panel module for positioning the LCD panel module in the accommodating area; and a front casing engaged with the rear casing and having a hole disposed at the center of the front casing, for displaying an image on a display surface of the LCD panel module.

2. A display casing capable of accommodating LCD panel modules of different sizes, comprising: a rear casing including a plurality of first positioning portions disposed on an internal side of the rear casing, wherein the first positioning portion is a groove disposed concavely on the rear casing and includes at least one first hook portion disposed in the groove; a plurality of adjusting portions each including a support stand and an elastic plate, wherein at least one second positioning portion is disposed at a distal side of the support stand and coupled with the first positioning portion, such that the support stand is fixed onto the rear casing, and the elastic plate is fixed onto a lateral side of the support stand; the second positioning portion includes a second hook portion disposed at a position corresponding to the first hook portion, and the second hook portion is a plate, such that when the second positioning portion is embedded into the first positioning portion, the first hook portion is coupled and fixed with the second hook portion; and when the second positioning portions of the adjusting portions are connected to the corresponding first positioning portions, the elastic plates of the adjusting portions form an enclosed accommodating area for accommodating an LCD panel module inside the accommodating area, and the elastic plate abuts against edge of the LCD panel module for positioning the LCD panel module in the accommodating area; and a front casing engaged with the rear casing and having a hole disposed at the center of the front casing, for displaying an image on a display surface of the LCD panel module.
